I’ve tried threadlib/docs/DesignOfThreadlib.md example:
use <threadlib/threadlib.scad>
MY_THREAD_TABLE = ["M4-int", [0.7, -2.1095, 4.1095,
[
[0, 0.3465],
[0, -0.3465],
[0.43304671, -0.09648036],
[0.43304671, 0.09648036]
]]];
thread("M4-int", turns=1, table=MY_THREAD_TABLE);
Got a lot of warnings and nothing is created:

I’m trying to understand this documentation to create my own thread (diameter 21.4, pitch 907)

Check your brackets: You forgot the outermost [... ]. MY_THREAD_TABLE must be a list of thread specs, even if you have only 1 thread spec. This should work:
use <threadlib/threadlib.scad>
MY_THREAD_TABLE = [["M4-int", [0.7, -2.1095, 4.1095,
[
[0, 0.3465],
[0, -0.3465],
[0.43304671, -0.09648036],
[0.43304671, 0.09648036]
]]]];
thread("M4-int", turns=15, table=MY_THREAD_TABLE);```
